Answer:
how is this a math question? ;-;
Number of pennies:P
Number of nickels:N
Number of dollar bills:D
P=N+12
N=D+5
1P+5N+100D=996
^given
Therefore
P=(D+5)+12
P=D+17
Plug back into main equation
(D+17)+5(D+5)+100D=996
Combine like terms
106D+42=996
106D=954
D=954/106=9
9 Dollar bills
N=D+5
N=(9)+5=14
14 Nickels
P=N+12
P=(14)+12=26
26 Pennies
26*1+14*5+9*100=996
Final answer:
9 Dollars
14 Nickels
26 Pennies

The answer is D. 3
Step-by-step explanation:
A number refers to the expression of a quantity or a magnitude. In mathematics, a number represents a fixed quantity of something or generally of a number system.
The numbers have a fixed order that determines their value.
The numbers are in order of:
Unit = 8
Ten = 3
Hundred = 5
Unit of thousand = 7
Ten thousand = 2
Hundred thousand = 4
Million unit = 1
10 million = 4
And a hundred million represented by = 3.
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12
